Another question regarding my basement bathroom build. The vanity we want won't fit in the spot where the current drain is so I want to move it over about 5 feet to the right of where the stack is in the picture below. I'm concerned with distance from the stack, it will be about 6 feet after it's all done. It's a 1 1/2"" stack, the main stack is on the other side of the house. The drain already there is sloped, so I was hoping to just be able to put a coupling on that end then continue the drain to where it needs to be, between the 3rd and 4th stud to the right.
